INTERNAIi-EXPLOSION ENGINE.

Specification of Letters Patent.

Application filed January 19, 1914, Serial No. 813,124. Renewed New To all whom it may concern p Be it known that I, CQNRADIN ALFRED BREITUNG, a citizen of the United States, and resident of Seattle, King county, Washlngton, have invented certain new and useful Improvements in Internal-Explosion which the following is a specification.

My invention .relates to internal explo sion engines and comprises certain novel constructions and combinations of parts which will be hereinafter described and particularly pointed out in the claims. 7 he objects of my invention are to improve the efiectiveness of the apparatus as a generator of power and particularly along the line of a higher compression of the 'tion through the water injecting valve.

the accompanying drawings I have shown my invention in the form which is now preferred by me.

apparatus by which this is Flgure 1 is.a sectional elevation taken on the anal plane. Fig. 2 is a plan view of the engine. Fig. 3 is a transverse sectional elevation taken through the impact wheel which forms the main rotor and through the final charge-compression cylinder. Fig. 4 is a transverse sectional elevation taken through the chamber which mary air-compressing rotor. 'Fig. 5 is a fragmentary section showing the emergency or relief valve which communicates with "the charge-compressing cylinder. Fig. 6 is an end elevation. Fig. 7 is a longitudinal sec- 1s a transverse section through the water injection valve. 'My engine contains as its principal parts, a main rotor or power producin member by which the other parts are turned, a primary air compressing rotor turned by the main rotor and whic gives the air a preliminary and relatively slight compression, and a final air compression piston, the chamber of which is also employed as an explosion or combustion chamber, fro'mwhich the products of combustion are discharged upon the maln or power developing rotor.

e mam rotor 1 is herein shown as an impact wheel'mounted upon the shaft 10. his rotor, as shown, has 1ts periphery provided with a large number of pockets 11, into which the products of combustion are discharged from the combustion chamber 2 through a port 12, which is controlled by a 'cular in outline but contains the priuntil seated in the surface 38 of the piston blade 31, also acts .cam surface 37,

peripheral inner wall is for a considerable distance, a close fit to the periphery of the rotor 1. Almost immediately after leaving the port 12, the inner peripheral wall of'this chamber gradually separates or is removed from closeness to the peripheryof the rotor, thus formin a discharge channel 14 of rapidly enlarging section, which will freely convey the gases to the discharge opening 15.

Secured to a continuation of the shaft 10, is the primary air compression mechanism, which is shown in Fig. 4. This should be of a rotative character, as it is to be operated by direct connection with the rotor 1. As shown it employs a chamber 3 which is cireccentric to the shaft. Upon the shaft is a head 30Wh10h has a slot extending therethrough transversely of the shaft, in which slot a piston blade 31 reciprocates,also transverse of the shaft.

The ends, or heads, 0 the. chamber 3 have each a circular groove 35, extending to the periphery, in which rollers 36 travel, these rollers being journaled upon an edge of the piston plate 31, whereby this edge of late 31 1s ke t in close contact with the perip er'y of the c amber. The air inlet for this chamber is at 32 and the outlet through the port 33. A gate 4 is pivoted at 40 and may swing inward so as to rest upon the curved camlike surfaces 37 of the head 30, or outward recess 34. The curved as a cam surface in combination with the outward.

In operation, the air entering through port 32 is swept around by the piston plate 31, compressed and driven out through the port 33, the gate 4 maintaining its swinging end in contact with either the head 30 or the piston blade 31 and preventing the air being drivenout through the port 32. The port 3 conducts the air to thefinal compression chamber 2. Ihave shown this of rectangular shape, although this may be round. Within this chamber is a piston 20, to which is attached a bar 21 having teeth thereon meshing With those of a gear 22 secured on a shaft 23. his gear may be only a fractional gear, as its duty is to reciprocate the to assist in moving this gate I I Q greases I I piston 20. l have provided a roller 24, bearjacket. The combustible fluid or gas is ining against the back side of the rack bar 21 jected through the pipe 7 into the comto hold it in mesh with the gear. pressed air. Spark plugs 8 are provided The main shaft 10, outside the case, has a for igniting the charge. The means for partial or interrupted gear 16 secured there controlling the action of these two mechto, its teeth meshing with those of a pinion anisms are not shown. They may be any- 17, to which is secured a crank arm 18 which thing which is found suitable and desired. is connected by a link 19 with a crank arm 4 A charge having been compressed within the 25 secured to a shaft 23; to which the pinion chamber 2 and, ignited, the valve is opened 10 22 is also secured. Crank arm 18 is shorter to discharge the gases upon the buckets or than that crank arm 25 to which it is convanes 11 of the wheel 1, turning this. The nected by link 19 so that a complete revoluprimary air compressor forces a charge of tion of wheel 1 will cause a to-and-fro air into chamber 2 while the piston 20 is oscillation of arm 25 and of the wheel'22 drawn back. The engagement of the inter- 15 which is secured thereto through the shaft rupted gear 16 with pinion 17 starts the 23. The partial gear 16 is proportioned to levers'which operate the valves and also the pinion 17, so as to give the latter one advances piston 20, thus completing the complete turn at each revolution of wheel cycle. The time at which ignition occurs in 16, but this is confined to a portion only of the chamber 2 is before the piston 20 reaches aa-the time of turning of wheel 16. The port the end of its compression stroke, say at 33 which connects the primary compression about 75% of the length of stroke. The chamber 3 with the final compression and full stroke should continue until the face combustion chamber 2, is controlled by a of the piston approaches as close to the end sliding or gate valve 5 which is attached to wall of the chamber as is found practicable. one end of a pivoted lever 1 y a Stem 50- I provide a valve 9 which controls a passage The lever 51 is rocked by a crank 52 which leading direct from the chamber 2 to the is secured to one end of a shaft 53. To the exterior, which may be used as a manually other end ofthe shaft 53 is secured a tappet controlled relief valve. This valve opens or cam lever 54 which is in position where against the pressure in the chamber and thus an it is engaged and controlled by the end of will open to admit air from the exterior at the crank arm 18. A spring 56, acts upon the beginning of the return stroke of the the tappet lever 54 to draw its end down, piston 20, or until communication is ,re which acts to close the valve 5. This occurs established with the primary compression at the beginning of the forward movement chamber 3. Exteriorly the stem of this of the piston 20 and the valve remains closed valve is engaged by a lever 90, by which until after the piston begins its return movethe .valve may be held off its seat, so that ment, that is, until arm 18 has passed into the compressed charge of air may be libcontact with the lever 54 toward the comerated, in part or wholly, should this be pletion of its rotation, when it rocks the desired.
